This method is commonly used in the surface treatment process of seamless steel pipes. It does not require DC power supply and special fixtures. It can polish parts with complex shapes and has high productivity. Chemical polishing can obtain a surface with physical and chemical cleanliness, and can also remove the mechanical damage layer and stress layer on the surface of the seamless steel pipe to obtain a surface with mechanical cleanliness, which is beneficial to prevent local corrosion of parts, improve mechanical strength, and prolong the use of parts. life. Because there are many varieties of seamless steel pipes, and different grades of seamless steel pipes have different corrosion laws, there are many types of chemical polishing solutions for seamless steel pipes, and the basic components include corrosives, oxidants and water. Corrosive agent is the main ingredient, if the seamless steel pipe is dissolved in the solution, the polishing cannot be carried out. Oxidants and additives can inhibit the process, allowing the reaction to proceed in a direction that favors polishing. Water regulates the concentration of the solution and facilitates the diffusion of reaction products.
